◆ Integrations

Every channel. One tablet.

Zay-OS plugs into the systems your kitchen already runs — your POS, the delivery marketplaces, Stripe for payments, DAVO for sales tax, Google + AI search for discovery. Direct orders, Uber Eats, DoorDash, Grubhub, and phone-ins land on one screen in one ticket flow.

Quick answer

Zay-OS integrates with Otter (which connects 25+ POS systems including Toast, Lightspeed, Square for Restaurants, Clover, and Revel), Uber Eats + DoorDash + Grubhub for marketplace ingestion, Stripe Connect for payments (operator keeps PCI scope with Stripe), DAVO for automatic sales-tax set-aside in all 50 states, Google Business Profile + AI engines (ChatGPT, Claude, Perplexity, Gemini) for discovery, and Twilio + Resend for customer comms.

Why Otter sits at the center

No new tablet. No new workflow.

Every restaurant we onboard already runs a delivery tablet. Otter is what lets Zay-OS pour your direct orders into that same tablet alongside the marketplaces, and what lets your menu cascade out to Uber Eats, DoorDash, and Grubhub the moment you change a price. One source of truth (your menu in Zay-OS), one destination (your kitchen tablet), every channel in between.

What flows IN to your tablet

◆ Direct orders from your Zay-OS site
◆ Uber Eats orders
◆ DoorDash orders
◆ Grubhub orders
◆ Phone-in orders the host took

What flows OUT from your menu

◆ Menu push to Uber Eats, DoorDash, Grubhub
◆ Hours + 86 ("we are out") in real time
◆ Price changes propagated everywhere
◆ Photo + description sync
◆ Order push into your POS

Integration questions

What operators ask first.

Do I have to switch off DoorDash and Uber Eats to use Zay-OS?

No. The marketplaces stay for discovery. On Operator + Marketplace and Concierge, Otter ingests Uber Eats, DoorDash, and Grubhub into the same kitchen tablet as your direct orders. You decide how much volume you steer to direct ordering over time.

What if my POS is not on the list?

Otter supports 25+ POS systems including ones most platforms skip. If yours is exotic, the kitchen tablet runs as a standalone flow so you are never left out. Tell us your POS before you sign and we will confirm.

Does Zay-OS work with my existing Otter account?

Yes. If you are already on Otter, we connect Zay-OS to your existing organization so your menu sync, order ingestion, and POS push continue without disruption. If you are not on Otter, we provision it as part of onboarding.

Who handles PCI compliance for my direct orders?

Stripe. Card data never touches Zay-OS — Stripe Connect handles the card capture and storage, so your PCI scope stays with them, not you. You get the receipt and the payout; Stripe gets the regulatory burden.

How does Zay-OS make sure my sales tax is collected and remitted?

DAVO sets aside the sales-tax portion of every direct order daily into a separate holding account, then files and remits the tax when it is due. Covers all 50 US states. The tax never sits in your operating account, so an unexpected state bill cannot drain you.

Can I trigger custom workflows when an order arrives?

Yes. Zay-OS exposes outbound webhooks for every order lifecycle event (placed, accepted, ready, picked up, refunded). Pipe them into Zapier, Make, n8n, or your own internal tool to fire SMS, accounting entries, kitchen displays, anything.
